ZZ TGANDES'GENT GAS-MANTLE.

To all whom it may concern:

Be it known that l, EWALD Ross, menufaoturer, a subject of the Emperor of Germany, and resident of Bel-men, Handelstrasse Rhenish Prussia, Germany, have invented new and useful Improvements in or Relating to Incandescent Gas-Mantles, of which the following s. specification.

It is the object of the present invention to provide an incandescentres mantle the body of which or carrier for the illuminating element is formed of interiors-d knitted.

blinds, cords, braids or the like, and which is provided with strengthening elements trsnsversely disposed to said body forming elements. These strengthening elements are in the some manner the body lGl'IIiMl of interlaced 'thre:1ds, cords or the like. The cords may be solid or tubule:- cnd threads may he interlaced, entwined or woven together so as to form a mantle body of great durability. A body of this construction is adapted to give a much brighter and more intensive light than is given by mantles of the known constructions because the illuminating element is more uniformly distributed in the body and adheres more intimately to the s me, thus forming an elastic structure liable to breakage and wines promises a greatly inrproved light. Finally when passing the mantle through the impregnating rollers its strengthening element will not he the cause of tearing holes in the hodypf the mantle as frequently happens in the manufacture of the customary insntlesf ss the tubular cords and interlaced three-'ls forming the strengthening elements will yield elastically when passing between the rollers, said tubular cords moreover are suitably adapted to receive and 'hold a considerable qiientity of the impregnating fluid.

In the accompanying drawingz l igure 1 shows part of a msntleoody composed of interlaced bands each which is formed of Patented res. ii, leis.

interwoven threads. Fig. 2 is a similar view showing part of a mantle body formed of interlaced bands and having strengthening elements interwoven therewith each of which is composed of interlaced threads, and Fig. 3 shows in its lower portion a combination of the elements shown in Figs. 1 and 2 and in its upper portion the strengthening elements interwoven with the elements shown in Fig. 1.

The mantle bod is composed of interlaced bands, stran s or braidsa, 6, each of said bands being formed of interlaced threads 0.

As shown in Fig. 2 strengthening elements d, e are provided which are disposed in the mantle body in the ordinary well. known manner and each of which is come posed of interlaced bands 7 formed of intenmust be flattened by stretching the fabric.

upon a suitable former or mandrel.

I claim:

An incandescent gas mantle comprising a body carrier for the illuminating element, interlaced, knitted bands forming said body,

strengthening elements transversely to sold body forming elements, and, interlaced threads for forming said strengthening elements, substantially as described.
